American Idiot cast perform "When September Ends" in tribute to victims of 9/11

In a tribute to the victims of 9/11, American Idiot cast members Alexis Gerred, Aaron Sidwell and Steve Rushton have recorded a cover of Green Day's "When September Ends".

The video is filmed in the auditorium of the Arts Theatre, where American Idiot is booking until 22 November 2015.

The award-winning Broadway musical - which features the music of Green Day with the lyrics of its lead singer Billie Joe Armstrong, and a book by Billie Joe Armstrong and Michael Mayer - tells the story of three boyhood friends, each searching for meaning in a post 9-11 world.

Its hit songs include "Boulevard of Broken Dreams," "21 Guns," "Wake Me Up When September Ends," "Holiday" and the title track "American Idiot".
